RAILROAD TIE AND CLAMP.

SPECIFICATION forming part of Letters Patent No. 609,848, dated August 30, 1898. Application filed Jamm 27, 1898. Serial No. 668,167. (No model.)

T0 at whom it may concern:

Be it known that we, CHARLES SWAN and JOSHUA G. GRAY, citizens of the United States, residing atrHillside, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Railroad Ties and Clamps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same.

Our invention relates to novel improvements in combined ties and clamps for railroad-rails; and the object is to improve the construction and increase the efficiency and durability of the same.

To these ends the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully described, and particularly pointed out in the claims. a

The accompanying drawings show our invention in the best form now known to us, but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of our invention as set forth in the claims at the end of this specification.

In the several views of the drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of our improved tie and clamp. Fig. 2 is a bottom plan View. Fig. 3 is a longitudinal section through the tie. Fig. 4 is a transverse section at right angles to Fig. 3.

1 denotes the lower section of the tie, which is preferably rectangular in formand is provided with a longitudinal pocket or recess 2 to receive a series of packing-strips 3 3, which may be of paper, cardboard, vulcanized or indurated fiber, or the like.

4 represents the top plate, formed with a shoulder 5, which snugly fits the recess 2, and it in turn is formed with a longitudinal pocket or recess 6 to receive a series of packin g-strips 7. A central bolt 8 extends through the top plate and tie to bind the two together.

9 and 10 denote the usual rails, and12 12 denote separable clamps, which are counterparts, being identical in construction, each beingformed with a recess 13 to receive the contiguous flange of the rail. Each clamp is formed at one end with a depending lug 14-, which extends below the projecting flange 15 of the top plate 4, and its inner face 16 is beveled inwardly and transversely, as shown. The opposite end of the clamp is also formed with a depending lug 17, which is provided with an integral right-angular key 18, the up per inner edge of which is formed with a transverse rabbeted recess 19 to receive the flange 15 of the top plate. The outer face of this key 18 is beveled downwardly and inwardly, as shown, to correspond to the beveled face 16 of the lug 14 on the opposite clamp. It will thus be seen that these wedgeshaped keys interlock with the lugs 14 on the opposite clamp, and when the bolts 20 20 are screwed up the clamps are drawn together to bind the rail to the tie and at the same time impart a longitudinal movement in opposite directions to the clamps to firmlybind the tie between them, or, properly speaking, rigidly bind or clamp themselves to the tie.

The clamps 21 and 21,which are shown fixed to the rail 10, are the same in principle as those just described, the only difference being that in this case the wedgeshaped keys 23 23 are separate, but when drawn together by the bolts 24: 24: said clamps operate in identically the same manner as those first described.

Having thus fully described our invention, what we claim as new and useful, and desire to secure by Letters Patent of the United States, is

1. The combination with the tie 1 formed with the longitudinal r'ecess2, of the top plate 4: formed with the shoulder 5 having the re cess 6, the packing fabric 3, 7, and means for removably securing said top plate to said tie, substantially as shown and described.

2. The combination with a tie formed with parallel flanges 15, 15, of the rail 9, the clamps 12, 12', each formed with a transverse recess 13, a depending lug 14 having an inner beveled face. 16 and a depending lug 17 formed with a right-angular key 18 having the rabbeted recess 19 and means for securing said clamps simultaneously to said tie and rail, substantially as shown and described.

In testimony whereof we have hereunto set our hands in presence of two subscribing wit- DGSSOS.

- CHARLES SWAN.
